Four tumblers of different sizes and two stemmed glasses to accommodate the best wines, guava juice, champagne, sparkling water or, why not, Fernet-Branca. Artisanal manufacturing gives each glass a handmade charm. The composition of the glass, based on borosilicate, combines two qualities which may seem contradictory: extraordinary lightness and very high strength. They thus resist all clinking. 100% Borosilicate.
